Answer:
14
Step-by-step:
A triangle has 3 sides, 2 of which we know and need to use in this question, i.e, 8√7 and X (which we need to solve for).
X is opposite to that 45° angle, which makes it the "opposite" and the 8√7 is the "hypotenuse"
When solving questions like this one, remember the acronym SOH CAH TOA which means: sinσ =
cosσ =
tanσ =
NB: σ= the known angle
(4x + 20) + (x - 10) = 180
4x + 20 + x - 10 = 180
5x + 20 - 10 = 180
5x + 10 = 180
5x = 170
x = 34
Answer:
the first 2 one is put on the right and the other on the left and the second 2 but one in the middle and one on the left!
Step-by-step explanation:
85700
8570
85.7
8.57
0.857
Each time, you divide by 10 (move the decimal place 1 place value to the left).
The answer is 60.
1(60)/60
=60/60
=1
